i I IGNITION APPARATUS.

a lication filed April 22, 1922. .Serial No. 556,122.

To all whom/ it may concern." I

Be it known that I, J OHN H. SrANnuRe, a citizen ofthe United States, residing at the city and county of Jackson, State of Michigan, have inventedoertain new and useful Improvements in Ignition Apparatus, of which the following is a specification. I

v This invention relates to improvements in ignition apparatus. I

The main objects of the'invention are 1 I First, to provide an'improved ignition apparatus comprising timing and distributing mechanism which may be opened for inspection without affecting itsoperationand so that it may be inspected while operating.

Second, to provide an 7 improved "ignition apparatus in whichjthe" mechanism carrying the distributor contacts and to which the cables are connected constitutes a housing for the operating mechanism. so that such partsfmay be fullyexposed for cleaning or adiustinent while in assembledrelation.

Third,"to provide in an ignition mechanism an improved distributonmember to "which the cables are connected so that short structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the The invention is clearly defined and pointed out in the claims. I p j A structure which is a preferred embodiment'of my invention is clearly'illustrated in the accompanying drawing forming a part of this application. in which:

. Fig. I is aside elevation of my improved Fig. II is a plan-view withthe cap .re-

Fig. III is a vertical section through the annular'distributor member and cap on a line corresponding to line" 3- 3 of Figs. I a'ndII.

' i Fig. Iv isg a det -ai'ls ide,elevati'en'with the cap and distributor, member removed exposing the operating parts foradjustment and cleaning. 7 I I I p In the drawing similar reference charactersrefer to similar parts throughout the several views. T I

Referring to the drawing. the body 1' is provided with an. annular shoulder 2 on which the annular distributor member 3 is seated. This annular distributor member 3 is formed of insulating material and constitutes a housing for the timer and distributor mechanism.

The cape is removable from the distribmounted on the spindle 10 which also carries the distributor finger 11 having a brush 12 thereon. The contact point 13 is suitably mounted on the breaker plate 14, the coacting contact 15 being mounted on the lever '16. actuated by the cam. As the details of these'parts form'no part of this invention thevare not further described.

'Thel distributor member 3 is provided with distributor'cable contacts llmounted to coact with the brush 12. The distributor cable sockets 18 are'suitahly spaced about to face downwardly so that the cables 19 are directed upwardly as they enter the sockets.

The distributor member 3 also carwas a terminal member-20 which is ordi- The timing mechanism is mounted on the body member 1, the breaker cam 9 bemg the distributor member 3 and are arranged narilv connected to the coil. The socket 21 .7

for this connection is also arranged to face downwardly.

A brush 22is mounted on the distributor finger 11 to coact with the terminal Inem- T ber 20. A 111223 on the cap 4 engages the terminal member 20 normallv supporting it.

With this arrangementof. parts the cap may be removed exposing: the mechanism within for inspectionso that the workmen may determine what manipulations are required. The distributor member 3 may then be removed and the parts are fullyexposed for cleaning or, adjustment or renewa'has may be desired. v v

f I have illustrated and provements in the form in which I have found very practical. 1 I have not attempted to illustrate or describe certain modifications or adaptations which I contemplate as .I believe the disclosure made will enable those skilled in the art to which my invendescribed my imtion relates to embody or adapt the same as may be desired.

Having thus described my invention, what I- claim asnew and desire to secure by Letters Patent, is
